Procedure
Dimethylformamide dimethyl acetal (0.73 ml.; d=0.087, 0.005 mole) is added slowly to a slurry of 8-methyl-6-phenylimidazo[1,5-d]-as-triazin-4(3H)-one (1.13 gm., 0.005 mole) in benzene (25 ml.). The reaction mixture is stirred, refluxed for 24 hours, cooled and filtered. The filtrate is evaporated to yield 1.4 gm. (100%) product. Recrystallization from methyl cyclohexane yields yellow crystals, found to be identical (ir; nmr) to the product obtained by Method A.
